[Freeswitch-users] Openzap extension can't use outside lines.

I obviously need to set a <variable name="toll_allow" value="domestic,international,local"/> somewhere but I can't figure out what file to put it in. The examples all show it in the directory/default/xxxx.xml files but those appear to be sip only. In any event creating files in that directory for my extension did nothing to help the problem. The only places I have the extension mentioned is in the openzap.conf file and dialplan/default/00_incoming-1.xml. Adding a <variables ... element to the latter does nothing. How do I set that variable? Or where? Thanks, Jim.
